Zoom Connection Unstable Fix – Stop Lag

Seeing the dreaded "Your internet connection is unstable" message in your big presentation? This is often a "Network Stack" buffer bloat issue on Windows, not your actual Wi-Fi speed. Againly fixes this automatically by flushing your DNS and resetting the WinSock adapter without interrupting your call.

Why this happens

• Packet Prioritization: Windows is giving "Windows Update" or background cloud sync priority over your Zoom video stream.
• DNS Bottleneck: Your ISP's DNS is slow to resolve Zoom's relay servers, causing a data backlog.
• WLAN Optimizer: Windows Wi-Fi drivers periodically scan for new networks, which causes a 1-second lag spike across active calls.

Fix it manually

1. Disable Background Sync: Open Task Manager > Performance > Open Resource Monitor > Network tab to kill data-heavy apps.
2. Use Google DNS: Change your adapter settings to use 8.8.8.8 and 8.8.4.4.
3. Registry Fix: (See our Network guide for the NetworkThrottlingIndex tweak).
